Experimental research on synchronized operation of 4 parallel-connected 1 GW nanosecond pulse generators is presented. With trigatron as trigger switch, the synchronized operation is successfully achieved. The jitter time of trigation is 0. 2 ns. The mutual spread of four 6 ns wide pulses is lower than 1 ns (probability above 95%) with an average value of 630 ps at a peak power of 1 GW (230 kV on 50Ω, load) of each parallel-connected module.%利用峰值功率可达1 GW的纳秒脉冲源CKP1000开展了4路GW级纳秒脉冲源同步技术实验研究.使用trigatron作为触发开关,通过单路开关触发特性实验研究优化了开关的结构与工作参数,单路开关抖动9.2 ns,建立了实验装置,实现了 4路GW级纳秒脉冲源并联同步输出.同步实验结果为:纳秒脉冲源输出电压230 kV,峰值功率1 GW,脉冲宽度6 ns,4路输出脉冲同步偏差95％以上概率分布在1 ns以内,平均同步偏差630 ps.
